file - Read the third string only java -

i have file example :

file.txt

milano tirana paris

madrid istanbul berlin

and want read third words of each line paris , berlin. tried substring won't work because length changes. how can ?

i'd recommend reading whole line, tokenizing splitting @ whitespace, , return index of value want.

something this:
